  A Convenient One-Pot Preparation of Benzo[b]-tellurophenes,-selenophenes, and -thiophenes fromo-Bromoethynylbenzenes

  摘要：

  2-Substituted and unsubstituted benzo[b]tellurophenes (3Aa-e) were synthesized in one-pot from o-bromoethynylbenzenes (2) via three steps in good yields. Similarly, benzo[b]-selenophenes (3Ba-e) and -thiophenes (3Ca-e) were also obtained.
